函数原型:int hibernate(void)
返回类型:int
参数:无
697 | nr_calls等于0 |
698 | bool snapshot_test = false |
700 | 如果非hibernation_available()则 |
705 | lock_system_sleep() |
712 | 打印信息("hibernation entry\n") |
713 | pm_prepare_console() |
714 | error等于__pm_notifier_call_chain(Going to hibernate , - 1, & nr_calls) |
715 | 如果error则 |
720 | ksys_sync_helper() |
726 | lock_device_hotplug() |
728 | error等于create_basic_memory_bitmaps() |
733 | 如果error或freezer_test_done则转到:Free_bitmaps |
736 | 如果in_suspend则 |
737 | flags等于0 |
739 | 如果hibernation_mode恒等于HIBERNATION_PLATFORM则flags或等于Flags that can be passed from the hibernatig hernel to the "boot" kernel in* the image header. |
741 | 如果nocompress则flags或等于SF_NOCOMPRESS_MODE |
743 | 否则flags或等于SF_CRC32_MODE |
746 | pm_pr_dbg("Writing image.\n") |
747 | error等于swsusp_write(flags) |
748 | swsusp_free() |
749 | 如果非error则 |
750 | 如果hibernation_mode恒等于HIBERNATION_TEST_RESUME则snapshot_test = true |
755 | in_suspend等于0 |
756 | pm_restore_gfp_mask() |
757 | 否则 |
758 | pm_pr_dbg("Image restored successfully.\n") |
761 | Free_bitmaps : |
763 | Thaw : |
764 | unlock_device_hotplug() |
765 | 如果snapshot_test则 |
766 | pm_pr_dbg("Checking hibernation image\n") |
768 | 如果非error则error等于load_image_and_restore() |
771 | thaw_processes() |
774 | freezer_test_done = false |
775 | Exit : |
776 | __pm_notifier_call_chain(Hibernation finished , nr_calls, NULL) |
777 | pm_restore_console() |
779 | Unlock : |
